Specification of Letters Patent'i 'Patented' S01; 28, 1909- Applicationfiled October 2, 1908. Serial No. 455,833.

To all whom it may concern:

Be it known that I, PHILIP A. Bin-111s, a citizen of the -.Unite(lStates. residing at Ashland. in the county of Ashland and State of Ohio.have invented certain new and mean Improvements in Spray-Nozzles. ofwhich the following is a specification. ret- -renre being had therein'tothe accompanying drawings. l

My invention relates to spray nozzles. and has for its object. theproduction of a nozzle of this character in which the packing will be soarranged. between the body of the nozzle and the cap therefor, that itwill be subjected to the pressure of theliuid within the nozzle and willnot be liable to be blown out or to be disarranged. Further, to pro videsuch a nozzle with n Hills for controlling the discharge in such amanner as to cause the same to form aspreading or um brella shapedspray; andv further; to pro ride a nozzle of this character having a disgorger and provided with positive means for limiting the stroke of thatdisgorger, thus enabling a short, qulck stroke to be imparted to thedisgorger to freethe discharge aperture from foreign matter.

d'it'h these ob ects in view'my invention consists in certain novelfeatures of construction and in certain combinations and arrangements ofparts hereinafter to be described, and then more particularly pointedout in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a nozzleembodying my invention: Fig. 2 is a front elevation of the same. withthe cap removed; Fig. 3 is an enlarged longitudinal, sectional view,taken tl'irough such a nozzle; Fig. 4 is a front elevation oil? amodified form of the nozzle, with the cap removed; and Fig. is alongitudinal. sectional View taken cent -'ally of a nozzle. such asshown in Fig. l.

In Figs. 1, 2 and 3 I have illustrated one embodiment of my inventionandhave shown the same as comprising a cylindrical body portion 1 having a screw-threaded side wall 2 and pr vided with an inlet which, inthe present. instance, comprises a'nipple 3 extending outwardly from therear wall. of the body portion 1 and provided'with a stufiing box 4:within which is mounted an inlet pipe 5 having a coupling 6 for securingthe same to a supply pipe. The-pipe 5 is slida-bly mounted in the nipple3, has its inner end closethas shown at 7, and is provided with-outletapertures 8 arranged near the rear wall of the cylindrical body portion.ii cap 9 is reinovably mounted on that end of the cylimlrical bodyportionopposite,

the inlet opening, preferably by 'providii'ig the same with an annularscrmv-thremlml flange 10 forming a side wall adapted to cooperate withthe screw-threaded side wall of the body portion. This cap is providedwith a centrally arranged outlet. opening it through which the tluid isdischarged. The body portlon 1 and cap 9 form between them a chamber 12,within which is mounted a disk 18 having one or more inclined apertures14;- adapted to receivev the water from the apertures S of the inletpipe 5 and discharge the same into the chamber 12 with a whirlingmotion. This disk may be supported in the chamber in any suitable man"nor, but, in the present instance, I have shown the same as having acentral screwthreaded aperture adapted to engage the screw-threadedinner endiof the inlet pipe 5. In the present form of the device, thisdisk 13 lies normally'in a position close to the rear wall'of the bodyportion 1 and I have here shown the rear wall as cut away, as shown at15, at a point adjacent to the apertures 8 in the inlet pipe 5, thusenabling the fluid to be discharged from the inlet pipe through thedischarge apertures'kl while the outer edge of the disk 13 rests uponthe rear wall of the body portion 1. A conical projection 16 is ar"anged centrally of the disk 13 on that side thereof adjacent to thedischarge aperture 11 in theeap 9 and so affects the movement of thefluid within the chamber 12 that the fluid will be discharged from thenozzle in the fOIIH Of a-spreading or umbrella shaped spray. In thepresent instance I have shown this projection as formed integral withthe inner closed end of the inlet pipe 5 and as having the form of afrustum ot' a cone. Mounted on the inner end of the projection 16 and inalinement with the discharge aperture 11 is a pin 17 of a length.substantially equal to the length of said discharge aperture. Thus, itwill be seen that by the movement of the inlet pipe '5 relatively to thebody portion 1, the pin the nozzle is c be apparent that the "inner endof the projection 16 face thereof is placed against the limb of a movethe body tree and the handle pressed forward to move the inlet pipe andthe disgorger" or pin 17 toward the aperture 11. As soon as the nozzleis released from the limb or other-objectagainst which it has beenpressed, the pressure of the fluid within the chamber 12 will portion ofthe nozzle away from .the. disgorger and into its operative 9 water withan annular recess o facap curing the same to a supply pipe.

packing parts of the nozzle.

faces of position. In order to provide a seat for the g which isemployed to render the between the body portion 1 and the cap tight, Iprefer to provide the body portion 1 with a seat or recess in which thepacking is disposed. In the present instance I have shownthe bodyportion 1 as provided with 'an annular. flange 18 extending outwardlytherefrom and having that face which lies adjacent to the screw-threadedside wall 2 of the body portion provided 19 adapted to receive oacking20. This recess 19 is preferably of a width slightly greater than thethickness of the inner. edge of the side wall 10 of the joint cap 9,which edge is adapted to engage the packin g which is supported in therecess v Thus,

it will be seen that the packing is placed at such a pint that it is notsubjected to the pressure 0 the water within the chamber 12 and isnotliable to be blown out or to become disarranged, but will maintain atall times a water-tight joint between the two In Figs. 4 and 5 of thedrawings I have. illustrated another form of nozzle, which is notprovided with a disgorger. In this form of the device the body portion21 is provided with a cylindrical side wall 22 adapted to codperate withthe cylindrical side wall 23 24 having a discharge aperture 25 arrangedcentrally thereof, the adjacent the side walls 22 and 23 of the bodyportion and cap, respectively, being screwthreaded to permit of theready separation or adjustment of these parts. The body portion is alsoprovided with a centrally arranged inlet 26 having a coupling 27 for se-An annular flange 28 extends about the rearportion of the body portion21 and is provided on the face thereof adjacent the cap 24 with anannular recess 29 adapted to receive a packing 30, the arrangement ofthe recess 1 scribed above m connection with Figs. 1 to 3.

A disk or partition 31 isa'r'riounted in thefrom the inlet 26=and isprovided chamber formed between the body portion 21 v I and cap 24 and:as here shown, is permaa nently secured to the cylindrical side wall ofthe body portion at a point some distance with an inclined aperture 32adapted .to discharge the fluid into that portion of the chamber lyingwhirling motion. This disk is preferably between the disk 31 and the.cap'24 with a provided with a centrally arranged conical rojection, asshown at 33, the'apex of which is in substantial alineme'nt with thedischarge aperture 25 of the cap 24 and serves to control the dischargeof the fluid through that opening.

The operation of the device will be apparent from the foregoing.description and it will be seen that 'I- have provided a-nozzle of thischaracter which the packing is so arranged that it is not liable to beblown out or to become disarranged, thus maintaining at all times awater-tight joint between the body portion and the cap of the nozzle.

Further, it will be seen that I have provided means for so controllingthe discharge of the fluid from the nozzle as to cause the same to bedischarged in the form of a spreading or umbrella shaped spray; and thatI have provided a nozzle with a disgorger having a positive stop forlimiting the movement thereof and thus enabling the same to be actuatedwith a quick, short, stroke, materially facilitating the operationthereof.

I wish it to be understood that I do not desire .to be limited to thedetails of construction shown and described, for obvious modi-.

fications will occurto a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto. secure by Letters Patent, is
